Four clients are seated at a table when the nurse brings in medications for one client.
The nurse will determine identity by:

Choice A rationale

A stat medication order signifies an immediate and urgent administration of the drug, typically within 30 minutes of the order. This is for critical situations where delay could significantly impact patient outcome, requiring prompt action rather than nurse's judgment for necessity.

Choice B rationale

A PRN (pro re nata) medication order means "as needed.”. This type of order grants the nurse professional discretion to administer the medication based on their assessment of the patient's condition and the specific criteria outlined in the order, such as pain level or fever.

Choice C rationale

A scheduled medication order involves administering the drug at regularly prescribed intervals, such as every 8 hours or once daily. The timing is predetermined, and the nurse's primary role is adherence to the schedule, with less independent judgment regarding administration necessity.

Choice D rationale

A single-dose order is for a medication to be given only once at a specific time. This is often used for preoperative medications or diagnostic procedures. Like scheduled orders, the timing is set, and the nurse's judgment about the necessity of administration is not the primary factor.

Choice A rationale

Cranial nerve X, the vagus nerve, plays a crucial role in innervating the pharynx and larynx, influencing speech and swallowing. Observing the movement of the soft palate and uvula when the patient says "ahh" assesses the motor function of the vagus nerve, as its bilateral innervation is essential for the symmetrical elevation of these structures.

Choice B rationale

Having the patient stick out the tongue and observing for tremors or pulling to one side assesses the function of cranial nerve XII, the hypoglossal nerve. This nerve controls the intrinsic and extrinsic muscles of the tongue, and abnormalities can indicate nerve damage or neurological issues affecting tongue movement.

Choice C rationale

Using a wisp of cotton to brush over the eyelashes and observing for blinking assesses the corneal reflex, which involves both cranial nerve V (trigeminal, sensory) and cranial nerve VII (facial, motor). This test evaluates the integrity of the reflex arc rather than solely cranial nerve X.

Choice D rationale

With eyes closed, touching various areas on the face with a wisp of cotton and having the patient identify where touched assesses the sensory function of cranial nerve V, the trigeminal nerve. This nerve is responsible for transmitting touch, pain, and temperature sensations from the face.
